Product Overview

A torque converter transfers engine power to the transmission through fluid coupling, helping heavy equipment move off, accelerate, and handle changing loads. A heavy duty torque converter is used in machinery such as wheel loaders, excavators, and construction vehicles that work under demanding conditions.
For equipment distributors, repair workshops, fleet operators, and municipal contractors, choosing the right unit means checking more than the product name. Transmission compatibility, engine output, mounting dimensions, and working conditions all affect how well the unit performs and how long it lasts.

Frequently Asked Questions
Q: How do I choose the right torque converter for my machine?
A: Check the original part number, transmission model, and machine details first. If you don't have the part number, send us the machine brand, model, and photos of the original unit so we can check compatibility.
Q: Can the same torque converter fit different wheel loaders?
A: Not always. Wheel loaders may use different transmission systems, mounting sizes, and converter designs. Check the specifications for each machine before ordering.
Q: Why does a torque converter overheat or wear out too soon?
A: Possible causes include low or dirty transmission fluid, poor cooling, heavy loads, or problems elsewhere in the transmission system. It's best to identify the cause before replacing the converter.
Q: What details are needed for a bulk quotation?
A: Please provide the quantity, machine models, available part numbers, destination country, and any packaging or documentation requirements. This helps us confirm the product details and prepare a suitable quotation.
Q: What should I do if there's a compatibility issue after delivery?
A: Contact us with your order details, part number, machine information, and photos of the installed unit or the issue. We'll review the information against the confirmed specifications and discuss the next steps based on the order terms. When purchasing a heavy duty torque converter, confirming compatibility before shipment can also help reduce installation problems.
